performance MCP servers & tools

iOS leak hunting and performance investigation. Reads .memgraph (leaks(1)) and .trace (xctrace) files, classifies retain cycles against a 34-pattern catalog (SwiftUI, Combine, Swift Concurrency, UIKit, Core Animation, Core Data, SwiftData, RxSwift, Realm), surfaces a Swift fixTemplate snippet for each match, and bridges to source via SourceKit-LSP. Single-call build+boot+launch fixes the macOS 26.x leaks --outputGraph regression; replayScenario + captureScenarioState close the verify-fix loop. 31 MCP tools, 34 catalog resources, 5 investigation prompts. CI-gateable via verifyFix and compareTracesByPattern. Apache 2.0.
